Bunker Hill Day takes place on June 17 every year. It is usually observed in Boston, Massachusetts. The holiday commemorates the Revolutionary War battle that happened in June 1775. The battle was led by General William Howe who led 2,200 British troops and half that number of Americans were led by Colonel William Prescott. The British attacked near Bunker Hill and lost more than 1,000 men in the process. The American revolutionaries, unfortunately, ran out of ammunition and eventually had to fight the British bayonets just with the butts of their muskets. This holiday is a reminder of the bravery of the heroes.
